I haven't seen anything directly related to VLANs, but rather on CARP. We're using re, em, xl, bge, sk and even the dc drivers - as both vlandev and vanilla. Here's one of the PRs (there are a couple, but I think they're all referring to the same bug) http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/92776 The patch committed doesn't fix the problem on my end, though. As long as you don't touch the CARPs once they're up you're ok. For a never-changing network that we're running, that's ok. Besides, we have two CARP-machines, so if one hits the panic, the other does the job very well. -- Håkon
